BACKGROUND OF THE INVENTION

1. Field of Invention

The present invention relates to a compressible backpack, which may be reduced or expanded as needed by the user.

2. Description of Related Art

A backpack is a cloth sack that is carried on an individual's back that is secured by two shoulder straps. The backpack is utilized to carry items that may be a little heavier than normal and allows the user to place items in the backpack to be transported on their back. It helps avoid some of the strain on a person's arm or hands by carrying hand or simple shoulder bags. The backpack may be made of leather and cloth forming a combined composition of material. Backpacks are either framed or frameless depending on the style. The frames of a backpack such as external frames help to stabilize and position the backpack on an individual's back during use.

Students often use backpacks due to the number of books and other items that they may have to carry to and from or while at school. Backpacks have also been converted into rolling devices for travelers to allow them the option of rolling the backpack as opposed to carrying upon one's back. Various professionals may also utilize backpacks for cameras, equipment and other items. Outdoor enthusiasts who may be partake in hiking or camping activities also use backpacks.

Backpacks may include various compartments and straps may be used to adjust the width or configuration of the backpack. Zippers are used on backpacks to open and close the various compartments that may be incorporated on a backpack. Also straps may be available to wrap around the waist of the user to further secure the backpack into place.

SUMMARY OF THE INVENTION

The present invention relates to a compressible backpack comprising: at least one airtight sealable compartment; an air nozzle on each sealable compartment, where the air nozzle provides a means to withdraw air from the compartment; and a pump, where said pump connects to the air nozzle on each compartment and removes excess air from the compartment. The compressible backpack may further including shoulder straps. The pump may include either a hand pump or a battery operated power pump.

DETAILED DESCRIPTION

The present invention provides a compressible storage backpack that enables the user to increase storage capacity due to the ability to withdraw air from the storage compartment within the backpack. The backpack according to the present invention includes storage compartments with airtight seals and vacuum suction pumps that remove air within the storage compartments in order to increase the storage capacity.

FIG. 1 depicts a Compressible Backpack 10 according to present invention. As can be seen from the side view the Backpack 10 includes compressible storage Compartments 20, 22. The storage compartments 20, 22 each have individualized suction Nozzles 21 a, 21 b. The suction Nozzles 21 a, 21 b provide a means to attach a pump that removes air from the storage compartments 20, 22 and therefore increases the ability to store more items within the storage compartments 20, 22 and maintain a reasonable size of the backpack. The backpack includes Shoulder Straps 30 and may be worn on an individual's back as a conventional backpack. FIG. 2A depicts a top view of the backpack according to present invention, which shows the top view of the airtight sealable storage Compartments 20, 22. The storage compartments 20, 22 may be loaded with materials or items to be transported and after these compartments 20, 22 are filled, a pump is attached to the air nozzles 21 a, 21 b to withdraw the excess air from the storage compartments 20, 22 and therefore making a tight fit for the Backpack 10.

The pump utilized to withdraw air from the storage compartment may be a hand type pump or a battery operated power pump. Either pump may be readily available to withdraw air from the storage compartments.

As stated above, this backpack 10 is similar to a conventional backpack in that Shoulder Straps 30 as shown in FIG. 2B are utilized to carry and secure the backpack to an individual's back. FIG. 2C shows a front view of the Backpack 10 according to the present invention. A Zipper 26 visible from the front view opens and closes the openings to the backpack compartments. Furthermore, a Storage Net 24 is provided on the front side thereof to insert other items such as a water bottle or other materials that the user may desire to have readily accessible.

The key components of the compressible backpack according to the present invention are the airtight sealable Storage Compartments 20, 22, suction Nozzles 21 a, 21 b and the hand held pumps that are utilized to remove the excess air from the storage compartment. These components provide a unique backpack for hiking and traveling. The backpack may be used to carry multiple items but however once items are contained in the sealable compartments, the compartments may be compressed by removing excess air. The removal of the excess air therefore allows the user to have a larger storage capacity than a conventional backpack. The backpack according to present invention provides an airtight seal and therefore will prevent odor or discoloration of any items contained within the compartments. The instant invention has been shown and described in what it considers to be the most practical and preferred embodiments. It is recognized, however, that departures may be made there from within the scope of the invention and that obvious modifications will occur to a person skilled in the art.
